注:N一噪声; S1—旧容器与包装袋、S2一苯乙烯净化处理产生的废活性炭、S3一收集的尘灰、S4—钢筋料头、S5—边角料、S6—废品; G1一破碎搅拌废气(苯乙烯)、G2一混合废气(粉尘、苯乙烯)、G3一焊接废气、G4一固化废气(苯乙烯、非甲烷总经); 图2-2工艺流程图及产污环节图 主要生产工艺简述: (1)分散搅拌:项目外购的聚苯乙烯粒子与苯乙烯按工艺比例加入分散机内分散搅拌,搅拌成糊状。其中聚苯乙烯粒子一次整袋倒入搅拌桶,苯乙烯采用无泄漏泵投加到搅拌桶内,在搅拌桶内常温搅拌均匀。聚苯乙烯塑料粒子在分散机内均速搅拌,经搅拌叶片的物理性破碎,随后与苯乙烯形成糊状料。随后分装在塑料桶内,根据刻度计量,确保后混合工序一次混合的加料,不再分装称量。整个过程为塑料粒子与苯乙烯的分散搅拌过程,无化学反应,有少量苯乙烯散发出来。 (2)混合搅拌:塑料糊制好后,与石英砂、滑石粉、不饱和树脂、脱模剂、固化剂、玻璃纤维按工l艺要求配比送入2台捏合机内混合搅拌,搅拌过程为常温搅拌。固化剂、脱模剂、不饱和树脂同样以计刻度的方法加料,不需称量。石英砂、滑石粉从原料储罐中以计刻度的方法加料,玻璃纤维加料,拆包后以整袋加入的方法代替称量(即根据包装重量计量)。 (3)骨架焊接:项目细钢筋与粗钢筋经加工制作成井盖的骨架,项目钢筋外购时为定长切割料,厂内不再切割直接使用。根据井盖的形状,方形井盖直接由定长的钢筋按工艺要求按田字格形状焊接即可;圆形井盖由定长的钢筋按工艺要求按田字格焊接结束后,外圆加焊一道细钢筋圆圈。 (4)装模、固化:装模过程,由锻压机打开模具,先放骨架,后人工加上混合料,合模压制,中温固化,自然冷却后即可开模。装模过程仅考虑装模时苯乙烯挥发产生少量苯乙烯废气。 模具采用电加热。固化温度约为150℃,固化时间约为5~15min,根据苯乙烯的物化性质,苯乙烯作为不饱和树脂的交联单体,在热、光或过氧化物作用下容易聚合,一般在50℃以上开始聚合硬化。固化剂为不饱和树脂交联固化过程中的引发剂,促进混合料的交联固化。整个过程中为加热状态下交联固化的化学反应。 (5)修边、检验 固化后的井盖,锻压机开启模具,由内部的锻压顶杆顶出井盖,极少量的飞边人工修剪,同时检验,首先人工肉眼检查混合料在压制过程中是否流动均匀,确保井盖的完整性,不漏骨架,井盖正面花纹或字体完全,再抽检荷载,确保产品符合国家质量标准。 包装入库:对成品进行检验,在经人工抽检合格后,打包入库成为成品,待发货。 项目变动情况 根据《建设项目竣工环境保护验收暂行办法》、《建设项目竣工环境保护验收技术指南 污染影响类》、《污染影响类建设项目重大变动清单(试行)》有关要求,建设项目的性质、规模、地点、生产工艺和环境保护措施五个因素中的一项或一项以上发生重大变动,且可能导致环境影响显著变化(特别是不利环境影响加重)的,界定为重大变动。根据验收现场勘查,对比项目环境影响报告表设计情况,现将企业变动情况逐项进行说明,本项目实际建设过程中变化情况详见下表。 表2-6重大变动情况一览表
通过以上分析,本项目的变动不会增加污染因子,污染物排放总量也在核定的总量范围之内。故本项目变动不属于重大变动范围之列。 |
